There will always be people who stand by the Last Of Us-esque moments, but it is encouraging to see more and more of the industry shifting towards more mature content(as in intellectually stimulating, not blood and guts) and openness in development.

The point is, whenever someone says "it's a mature game", he or she means in fact : "This game is violent". Nothing else.

"Matureness" of games can be

- intellectual
- about art
- about politics

etc. . A game isn't necessarily "mature" if it contains lots of violence.

But everybody says so.

I believe that it is a good idea to read these comments there, too.
And of course the "controversies" article itself. Especially its last part.

On sexism, I quote this :

But what was truly horrifying was the backlash, with vocal online communities mounting hate campaigns and viewing intimidation and harrassment of Sarkeesian as a personal mission. Someone even made a Flash game about beating her face black-and-blue.

-- “ Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius – and a lot of courage – to move in the opposite direction.“ (E.F.Schumacher, Economist, Source)
